To all whom it may concern: 1

Be it known that I, J 01in W. COSGROVE, a citizen of the United States, residing at Medford, in the county of Middlesex and State .of Massachusetts, have invented certain Imous objects, it bein of especial utility in the manufacture of s oes for coating with cement surfaces of considerable area which may be of diiferent thickness and somewhat irregular and from which particles may be dislodged in the cementing operation.

itself to the attainment of the desired results is found in a pressure device, preferably consisting of a plurality of independently movable members fulcrumed upon a support which may be adjusted to control the relation of all the members to the work.

Another feature consists of novel means for clearing the cement-applying surface of accumulated particles from the work, this means being carried upon said cement-applying surface. In the form of the invention illustrated, the clearing means is furnished by a spiral projection upon the cement-applying roll. When in contact with a scraper, this causes the particles caught by the roll to travel to one side where they may be readily removed.

An embodiment of the invention illustrating these and associated features appears in the accompanying drawings, in which,-

Figure 1 is a front elevation of my improved apparatus, parts being broken away;

Fig. 2 is a top plan view with the driving mechanism removed; g

Fig. 3 is a transverse section on the line 33 of Fig. 1, and

Fig. 4 is a transverse sectional detail illustratin an alternative pressure device.

To hold the adhesive, a tank or receptacle 10 is provided, and to maintain the cement in the fluid condition this tank may have in its lower portion electrical heating units 11. Steam ma also be utilized to heat the cement, it eing introduced through a pas held in place by thumb screws 14 through slots in the cover plate and sage 12 above the openings which receive the units 11. The cement may be withdrawn from the tank, when desired, through openings normally closed by a cover plate 13 pivoted upon the end wall of the tank and being threaded into the tank wall. Journaled in the ends of thetank, passing through stuffing boxes 17, 17 to prevent the leakage of cement, is a shaft 16 upon which is fixed a drum or roll 15 of such diameter that its periphery reaches from a point near the bottom of the tank to its upper edge. Rotatable in a boss projecting from an end wall of the tank is a counter-shaft 18 carrying fast and loose pulleys 19,19 over which may operate a belt (not shown) driven from any suitable source of power. A shifter 2Q, mounted to One feature of the invention which lends slide upon a rod 21 fixed in a boss on the tank, serves to move the belt from one of the assing pulleys 19 to, the other. The shaft 18 carries a pinion 22 meshing with ,a gear 23. fixed upon the shaft-16. This gear rotates the cement-applying roll in the tank at a comparatively low speed. The gearing is inclosed in a shield 24, which not only guards it but also provides a support for activemembers of the apparatus, as will be later described. Upon the cylindrical surface of the roll 15 is a projection 65 by which the cement brought up from the supply at the bottom of the tank is distributed in a comparatively thin layer over the surface of the work. As illustrated, this projection is in the form of a right-handed helix of small pitch. The utility of this helical form will later be stated.

At the front of the tank is a combined.

work table and scraper 25 upon which may be laid by the operator the object to be coated, as a sole S. The member 25 is mounted to move in ways 26, it having a depending lug 27 at its outer end in w ich is mounted to turn ascrew 28, provided with face of the roll brought up into contact with the work may be varied and, when moved j suflicientl close to the roll, the member will catchan scrape off particles which have been thrown off from the work. Such particles accumulating tend to clog the scraper and gathering in the cement impair its quality. In my machine, however, .as they contact with the ed e of the scraper, the inclination of the helical projection 65- causes them to travel to one side of the roll along the edge of the scraper, in the present instance to the right. Here they may be removed by an end scraper mounted upon the top of the tank and being preferably adjustable with relation to the roll by clamping means consisting of screws 31 passing through slots extending in the direction of the axis of the roll. A secnd scraper 30 may also be provided at the opposite end of the tank from that at which the waste particles are removed to keep this end of the roll free from an excess of cement.

At the opposite side of the tank from the member 25 is a support for the coated ob-- ject, this being in the form of a grating 32 extending from end to end of the tank and secured to the top of the wall. Through p from the tabie.

the openings in the grating the cement from the objects S may drip to return to the supply at the bottom of the tank. Beneath the grating is a slide 33 extending over the top of the rear wall and reaching into proximity with the surface of the roll. This furnishes a closure for the tank-at this point to prevent evaporation of the cement. t the opposite side of the tank .the table 25 i effective for a like purpose.

From the end walls of the tank serving as a supporting frame, near the inner end of the table 25, rise brackets 34in which is fulcrumed a pressure member serving to force the work into contact with the cement- .applying roll. This pressuremernher pref- 45- erably consists of a carrier frame, which I have shown as made up of bars 35, 35 lying parallel to the axis of the roll, these bars being connected at their ends and pivoted in the brackets 34 upon a rod 37. Ihis rod also supports a piurality of rocking pre sure fingers 38 lying above the roll and having curved Contact faces 39 to engage the work as it is advanced by the operator The opposite ends of the fingers have upturned projections contacting at one I l with stop screws 41 threaded through the inner bar 35 of the frame. By these screws the limit dowry ward movement of the lingers may be changed to bring the contact faces 39 into horizontalalineinent. At the opposite of each projection 40'fror the far contacts with the screw rounded by a spring 42 which spring enters a QQIW 4.0.10

35. Each bore is threaded to receive a screw 43, which may be adjusted toward or from I the finger projection 40 to alter the tension of the spring so that all the fingers may be adjusted to press upon the work with equal 35, 35 above the screws 41 and 43, preferably near the center, is located a pair of opposite contact screws 44, 44 the inner ends of which.

may be turned into engagement with a bar 45 connecting the upper ends of the brackets 34. By loosenin one of these screws and tightening the other, the initial position of the-pressure member as a whole may be de termined, so that all the pressure fingers 'may be simultaneously moved toward and from the upper surface of the work to adapt them for proper cooperation therewith when brings up cement from the supply at the bottom of the tank and distributes it in a uniform coating over the object, the engagement of the roll in its rotation drawing the work beneath the fingers and carrying it upon the support 32. feeding movement the contact surface of the projection 65 is preferably knurled. As the work goes on, loose particles from the objects operated upon gather upon the roll, and, if the adjustment of the member 25 is close to the roll, will be continually moved by the action of the helical projection to the To facilitate this force or to the extent desired. In the bars i right-hand end of the tank, where they are scraped from the roll by the member 30. If the adjustment of the member 25 is farther from the roll 15 and the operator wishes at any time to clear the surface of particles, the scraping edge may temporarily he brought into contact with the projection 65 by the screw 28 and there held until the helix has acted to transfer the accumulated particles to the field of action of the scraper 30.

if the material to be cemented is diifficult to feed, a positively driven pressure mem- )Qi may be provided. Such a device is illus- .ated in Fig.4 of the drawings, this con- .isting of roll 50 rotatably mounts" frame consisting of side bars cross bar 52. The frame is fr ,1: a red 53 which may h supporting rod 3'? n i ich of the side on and bet.- responding SC? springs 55-,

opposite ends of the roll 50 to force it toward the cement-applying roll 15 and against the work thereon. The roll 50 is rotated in the direction of the arrow by a belt 56 passing over a pulley 57 on a countershaft 58 journaled in a bracket 59 rising from the fixed upon it a pulley 60 over which runs a belt 61 to a relatively large pulley 62 upon the counter-shaft 18. It will be seen that the roll 50, rotating in the opposite direction from the cementing roll, cooperates therewith to advance the stock from the table 25 to the support The feed roll may be provided with such a surface as to give the best feeding engagement.
